Development of a recipe for wheat bread with an increased content of dietary fiber

Abstract

At present, there is a persistent deficiency of dietary fiber in the diet of the adult population of Russia. A promising source of dietary fiber is the by-products of oilseeds processing. The article proposes a method for enriching wheat bread with dietary fibers by introducing hemp meal, which is formed during the production of protein isolate from hemp cake and contains 57.5±0.4% dietary fiber. The aim of the work was to establish the optimal dosage of meal in the recipe of wheat bread by comparative analysis of organoleptic (appearance, color of the crust and crumb, porosity structure, taste, smell, chewability) and physico-chemical (humidity, acidity, crumb porosity, specific volume of bread) characteristics . The objects of the study were a control sample of bread made from premium wheat flour, as well as model samples of bread with various additions of meal. Standard methods were used to study the main qualitative characteristics of the control and model samples of bread. The optimal dosage of meal was established in the amount of 15% by weight of flour. A sample of bread with the addition of 15% meal was characterized by the compliance of organoleptic and physico-chemical parameters with the requirements of GOST R 58233-2018 “Wheat bread. Specifications". An increase in the content of dietary fiber in the optimal sample by 5.4% was found compared to the control sample. It has been established that eating 100 g of bread per day, obtained according to an optimized recipe, will satisfy the need for dietary fiber in an adult by 31.6-39.5%. The result of the study is an optimized dosage of hemp meal in the wheat bread recipe. This bread can be recommended as a source of dietary fiber.
